PHOTOGRAPHIC POSING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 435,056, dated August 26, 1890,

Application iiled May 29, 1889. Serial No. 312,533. (No model.)

To al@ whom it may concern,.- Be it known that l, JAMES M. DOW, a citizen of the United States, and a resident of Ogdensburg, St. Lawrence county, and State of New York, have invented new and useful ImprovementsinPhotographicPosing-Chairs, of which the following, taken in connection with the accompanying drawings, is a speci# fication. j

My invention relates to posing-chairs more especially adapted for photographers, although equally adaptable to other purposes; and it consists, in part, of the combination, with a suitable seat, of a series of adjustable parts, rest-supports, and braces, adapted for varied and independentadjustments forhead, back, dro.; also, in the construction and arrangement of said head and back rests, combined with other parts, whereby an independent vertical and lateral adjustment may be had; and, thirdly, in the construction and combination of the several parts whereby such chairs may be utilized with a greater degree of efficiency than when otherwise constructed, the object of which is to provide such chairs with such parts and adjustments that the subject to be operated upon may be posed more properly and to the desire of the photographer or other person posing or being posed than by any other known means, and at the same time insure the greatest amount of c omfort to the party being posed; hence my invention.

Referiingto the drawings, Figure l repre- Sents a perspective view of a posing-chair in accordance with inyimproved invention; and Figs. 2, 3, and 4 `represent perspective views in detail of parts to be referred to hereinafter. Fig. 5 represents a sectional view of the compound pivotal and clamping disk located at the upper end of the head and back rests vertical supporting-rods. Fig. 6 represents a sectional view of one of the vertical support ing-rods E and its tubular supporting-rod D:

Fig. 7 represents a vertical sectional view of theparts shown in Fig. 2.

In the drawings, A represents a chair to which my improved appliances are secured, and B B represent two rods which extend in a circle partially around and at a greater or less distance above the said chair A, and are secured at their opposite ends in suitable brackets A A', the latter being properly secured tothe opposite sides of the seat .0r frame thereof, as clearly shown in said Fig. l. Said rods B B serve as a means to propel or move the chair about and also as a track and fulcrum upon which couplings C C are supported and adapted to slide and operate and be secured in a stationary position thereon, when desired, by a set-screw. Said couplings C C are provided with right and left arms c c, which in the instance shown are provided with ears c c', adapted to embrace the "said rods B B and are secured thereon by bolts, as clearly shown in Fig. l, although it is obvious that the said arms may be secured by straps or other'suitable means, the object being to have said couplings secured on the rods B B in a manner to allow them to be moved laterally and also pivot or fulcruin thereon for the partial adjustment of the head and back rests, in a manner as will hereinafter be described. 1

D D are tubular rods which extend through and are carried and supported by said couplings C C, and the same at their opposite ends are provided with collars CZ "d, for the purpose to be hereinafter described.

F. E represent vert-ical supporting-rods for the back and head rests,which extend within said tubular rods D D and are adapted to 'slide or operate vertically therein and be held or supported in a stationary position by a setscrew located in the collar d on the upper end of said tubular rods D D. Said tubular rods at their lower end are provided with a fixed arm D', extending parallel, or nearly so, there-v from, which at their lower end have adjustable connection with horizontally arranged rods F F. Said arms D and horizontal rods F at their point of connection are each provided with a circular iiange or plate, as clearly shown in the drawings, adapted to be clamped together to adjustably hold said rods or arms in a iixed position relatively to each other by a thumb-screw, although it is obvious that other suitable means might be employed to clamp said plates together. When desired, the angles of the two rods maybe adjusted by loosening the thumb screw or other clamping means, as will appear obvious. Said Vhorizontally-arranged rods F F extend through and are adapted to slide in pivotalfsupport ing-sleeves, represented at G G. (More clearly shown in Fig. 2 of the drawings.) Said sleeves consist of a suitable plate provided with a lug or projection having `a longitudinalv opening therein through which the said rods pass, as clearly shown, and the same are pivotally secured to swiveled plates G G', the latter being swiveled, in the. instance shown, on a rod G3, supported at its center on the rung A2 of the chair, one abovethe other, and are held in position by nuts, as more clearly shown in Fig. 2, which represents an enlarged View in detail of the swiveled plates and supportingsleeves in reversed positions to more'clearly show the construction of the same. It is obvious, however, that said swiveled plates may have aseparate swivel-connection and to any suitable part of the seat or frame.

The said 'swiveled plates G G are provided at one end lthereof with a d'og G2, adapted to engage with serrations (represented at f) in the under side of said horizontal rods F F to prevent i the' latter from sliding` forward in their supporting-sleeves and to ad justably support the said tubular rods D D in a manner to allow Mthersameto be adjusted to a greater or less ldegree of incline to change the position of the back and head rests, as will hereinafter beimore fully described, and thel described adjustable method of connection between the `vsaid pivotal supporting-sleeves and swiveled supporting-plates "allows the said horizontal rods tobe raised from engagement with'the engaging-dogs foradj ustment of the back and '-'lread1rests, as will be hereinafter described,

' and also for the lateral adjustment of said rods, las will appear obvious. The said tubur lar rods D D are each provided with a Vcoiled spring H, located at a point between the coup- -ling C and the collar CZ, located on the lower 'fend of said tubular rods, and are adapted to exert a downward pressure on said tubular 1 rods to yhold the same in position and keep y the horizontal rods F F, having connection therewith, in engagement with the dogs G2 G2. J represents a compound sliding pivotal fand clamping disk, located and having connection with the upper end of the vertical :supporting-rods E E, adapted, in the present instance, for the adjustable support of the 'fw-head and back rest supporting-arms, (reprefsented at I and Z, respectively,) and consists of aplate or disk provided with an enlargel-Inentfthereon, having a longitudinal opening '-therein for the reception of a rod or bar, said A='enlargemei1t being cut away orpro vided with y 'an opening therein at a point between its l iends, communicating with the said longitudi- -nal opening therein, as clearly shown in Fig. 3, 1n which a clamping-'plate ,72 which' is by means of a thumb-screw, which also clamps- 1 -lthe said pivotal disk to a fixed plate js, (shown fin dotted lines' in Fig. 3,) located on the upper end of said rods EE. By thismeans the rods or arms supported in said pivotal clampingdisks may have a longitudinal adjustment therein, and be adjusted either up or down to change the position of the back or head rests by simply adjusting a single thumbscrew, as will appear obvious.

The head-rest, represented at K, (more clearly shown in detail in Figs. 4 and 3) consists of two arms 7c k, pivot-ally secured at their inn er ends to a plate 7o', as shown in Fig. 4, which is adapted to be Vclamped to a fixed plate oriiange 7a2, located on the end of a connecting-rod 7c3, with the ends of said arms between the two surfaces, by a thumb-screw, to clamp the inner ends of said armsand adjustably hold their outer ends in a fixed position and allow them to be adj ustedintheir relative position to each other. Said connecting-rod k3 at its opposite or inner end has a swivel-joint connection with the supportingrod I at 7a4, said joint consisting of two plates located on the connecting ends of said rods, adapted to be clamped by a thumb-screw or other Vsuitable clamping means to allow-fora further adjustment of the head-rest other than that allowed by the compound'pivotal clamping-disk J.

The adjustment of the back andheadfrests is accomplished as follows: The operator grasps the supporting-rods E E andmoves the rests either to the right or left around the subject, asy desired, and raises. the same up to the proper' height inrelation to the suhject, and secures the same lay-tightening the set-screws which hold said rods, as herein- IOO before described. Any minor adjustment of the said back and head rests is accomplished through the medium of the said sliding-pivotal clamping-disks, as hereinbefore `described.

To adjust the incline of the' supportingrods for the back and' headv rests the'operator raises said supporting-rods toraise the horizontal rods F F from engagement with the dogs G2 G2 and pushes the same backward or forward, as the case may be, and upon releasing the hold on said supporting-rods'the` springs H, located on rods D D, press Vsaid horizontal rods F F down in engagement with the dogs G2 G2.

Having thus setfforth my invention,'what I claim as new, and desire to secure by-Letters Patent of the United States, is*- TIO 1. The combination, with a' suitable seat, of

frame provided with horizontally-arranged supporting-rods extending around the same and supported thereby, of vertically-arranged supportingrods adj ustably supported in couplings, said couplingsbeing loosely mounted on said horizontally-arranged rods, and means for adjustably supporting the lower end of said vertical supporting-rods, whereby the back and head rests may have a vertical, lateral, and backward and forward adjustment, substantially as described, and for the purpose set forth.
